ANOMALOUS ORIGIN OF LEFT MAIN CORONARY ARTERY ORIGINATING FROM THE RIGHT SINUS OF VALSALVA: AN ANOMALY WITH FATAL OUTCOMES

Abstract

Anomalous coronaries are often rare and incidental findings. Patients with coronary anomalies can have a wide array of presentations varying from chest pain to sudden cardiac death. Anomalous coronary artery originating from the opposite sinus (ACAOS) has a low prevalence, but with the advancement of imaging tools, its accidental detection has increased. Here, we describe such a rare case of a middle-aged man with a permanent pacemaker in situ who presented with recurrent syncope. Cardiac catheterization identified an anomalous origin of the left coronary artery from the right coronary sinus, and a computed tomography (CT) angiogram identified a high-risk course of the lesion.
